No. 22,296 12 Claims. (Cl. 20-53) This invention relates to improvements in rotary type windows which permit reversal of the sash to facilitate cleaning of the inner and outer surfaces of the glazing.

In counteries having cold climates it is necessary to provide properly insulated window structures capable of being sealed or in close fit relation to prevent cold air from penetrating -into a house or other building as well as to retain the heat manufactured within the building.

One method is `to provide double windows and in more modern constructions, aluminum-framed windows and like window sashes have been preferred as a closure means for providing contact or closure with the frames, for the reason that they will not expand and shrink under varying temperature conditions in the manner of wooden sashes.

Nevertheless, until now aluminum type Iframes and sashes have had the same disadvantage as the wooden ones, with regard to cleaning the outer surfaces thereof. Certain conventional windows are provided with fixed frames and sliding sashes which require cleaning of the exterior face of the glazing fromI outside. Others provide means for removing the -sliding sashes so that they may be taken interiorly `for cleaning. While the latter type has an advantage for sashes of comparatively light weight, it is not practical for large and heavy sashes of the type used in commercial establishments since their weight and size makes them too awkward to be manoeuvered.

Another disadvantage of the latter type off sash is that no means can be provided for excluding cold outside temperatures during the cleaning operation.

The present invention proposes to overcome all of the aibove disadvantages. One object of this invention is to provide a window comprising a fixed main frame structure and a sash structure which is pivoted about a central axis to the opposite sides of the frame whereby the sash may 4be rotated to present its outer face to the interior of a building in which the frame is mounted to facilitate cleaning of the outer surface of said sash.

Another object is to provide Ia `frame structure of the character described with pivotally mounted shoulder flanges engageable with opposite surfaces of the sash at either side of the rotary axis of said sash and biasing means engaging said flanges so that, during rotation of the sash to its normal closed position, the frame will be compressed along its edges in contact with said ilanges against the pressure of `saidbiasing means, and during rotation of the frame in the opposite direction said biasing of the anges will exert an impelling pressure on the frame to facilitate rotation of the frame.

Proceeding now to a more detailed description, reference will beA had to the accompanying drawings, in which: ,j t l p FIG. l is a front view of a window embodying my invention.

FIG.v 2 is` a. side view with the sash in closed position. FIG". 3` is a "fragmentary section taken along line 3--3 of FIG. 1.

FIG. 4 is a fragmentary section taken along line 4-4 of FIG. 2.

FIG. 7 is a fragmentary section taken along line 7 7 of FIG. 6.

FIG. 8 is an elevation in detail of a bearing block on which the window is rotatably mounted.

Referring more particularly -to the drawings, numerals 5, 6 and 7 designate top, side and bottomy metal frame members in which a sash 8 is pivotally mounted for rotation about a central horizontal axis by means of pins 9 which are carried by bearing lblocks 10 slidably mounted on the outside of side frame members 6 in slideways 11 (FIG. 7). The bearing 4blocks 10 are T-shaped in cross-section, with the web protruding through an opening in said side frame member 6. Stops 12 (FIG. 5) piviotally mounted on the frame and abutted in closed position (FIG. l) by abutments 13, lock the blocks 10 on the frame.

A sash stop shoulder formed as a lange 14 projects downwardly from the top frame 5 and is offset outwardly of the vertical center plane of the Window frame (FIGS. 2 and 6) and a second llange 15 projects upwardly from the bottom frame member or sill 7 and is offset inwardly of the vertical center plane of the window frame; the amount of offset is such that when the sash is in its closed position it will be sealed at the top and 4bottom by said flanges 14 and 15, engaging recesses 23 and 24 respectively at the inner top and outer bottom of the sash.

A plate 16 is mounted on the outside of each side frame member 6 adjacent the upper end, to pivot about a horizontal axis pin 17 mounted on said frame member with its axis adjacent the lower tip of the ange 14. Plate 16 carries a shoulder flange 1S which projects through a sector-shaped slot 19 into the path of the upper half of Ithe sash and is receivable inV a recess 20 along the margin of the sash to provide a seal when the window sash is swung to its closed position. The plate 16 has a projecting pin 21 engaged by a lbent wire spring 22 anchored on the side frame 6 which normally biases said plate member 16 Ito swing inwardly about its pivotal axis. Spring 22 is formed with a bent hook 24 embracing the pin 21, and at its other end it is looped over and fastened by bolts 25 (FIGS. 3 and 7) which also serve to secure the slideways y11 to the frame.

Additionally a second plate 26 is mounted on the outside of side frame `6 adjacent the lower end to pivot about a horizontal axis pin 27 mounted on said frame with its axis adjacent the upper edge of the flange 15 mounted on the sill. Plate 26 carries a shoulder ilange 2S which projects through a sector-shaped slot 29 into the path of the lower half of the sash and is receivable in a recess 30 along the inner margin of the sash to provide a seal when the window sash is swung to closed position. Plate 26 also has a projecting pin 31 engaged by a bent wire spring 32 anchored in the side frame 6 to bias the plate 26 to swing outwardly about its pivotal axis. Spring 32 is mounted in a manner similar to spring 22 The ilanges 18 and 28 extend from the pivotal aXes of pins 17 an-d 27 respectively, to points short of the central axis of pins 9 by a distance which is slightly greater than the thickness of the sash, so that when the sash is in a horizontal position it may be removed from the frame by sliding out the bearing blocks 10.

The recesses 20 and 30 on either side of the sash have rounded out depressions 33 at their inner ends which Serve to receive initially the central ends of the flanges 18 and 28 when the sash is being rotated towards its normally closed position. As rotation proceeds during the closing of the Window, the biasing of the anges 18 and 28 through springs 22 'and 32 respectively, causes the sash to resist closure. Thus when the Window is ,fully closed the flanges provide an effective seal along the sides of the window.

When the window is being swung to its reversed position for cleaning the said biasing on the anges facilitates the rotation until contact of the flanges is broken at the depression 33 at the inner end of the recesses 20 and 30.

Each of the sector-shaped slots 19 and 29 has one radial edge vertical and aligned with the corresponding flange 14 or 15 and another radial edge inclined respectively outwardly and inwardly of the window frame. The vertical radial edges are designed to limit the pivotal movement of the plates 16 and 26 by abutting the anges 18 and 28 as the window is rotated to its normally closed position. The inclined radial edges serve to limit the pivotal movement of the plates 16 and 26 in the opposite direction, by abutting the anges 18 and 28 when the latter are in parallel planes spaced by a distance corresponding to the thickness of the sash 8. Thus when the sash is in its reversed position it abuts the flanges 18 and 28 to form therewith a seal which is by no means as perfect as the seal in the normal closed position, but which is useful to prevent excessive heat loss while the outer face of the sash glazing is being cleaned.

The plates 16 and 26 are of a size suicient to cover slots 19 and 29 in al1 the pivoted positions of the plates, and at the center the plates 16 and 26 overlap the central ends of the flanges 18 and 28 and the circumferential edges of the slots.

Means are also provided to lock the window in. its closed position. As shown in FIGS. 4 and 6 a latch pin 40 is slidably mounted in a bearing 41 secured against the lower face of the sill 7 by engagement with a casing 42 which contains the locking mechanism. The latch pin 40 is adapted to project through a bore in the sill 7, into a latch hole 43 to the bottom edge of sash 8. A coil spring 44 bearing against a cross pin 45 passing through the pin 40 and riding in a slot 46 of the bearing 41 urges the latch pin 40 into a retracted position. The 'lower end of the latch pin rides on a wedge block 47 slidably mounted on the bottom of the casing 42 and controlled through a connecting rod 48 by a knob 49. The wedge block 47 engages the pin 40 and raises it to operative position.
